Tropism

Tropism is a noun that refers to a tendency to respond to a stimuli. The Greek word tropos (TRO pose) means ‘to turn.’ Our word of the day is frequently used to describe plants and other organisms, but may also refer to tendency of people to lean toward the familiar. For example: Great movies about deep, intellectual topics are hard to come by. The tropism among moviegoers is toward mindless action movies. This could change in the future, but I suspect it won’t.
